LaTeX's default style of typesetting mathematics does not comply
with the International Standards ISO31-0:1992 to ISO31-13:1992
which indicate that uppercase Greek letters always be typset
upright, as opposed to italic (even though they usually
represent variables) and allow for typsetting of variables in a
boldface italic style (even though the required fonts are
available). This package ensures that uppercase Greek be typeset
in italic style, that upright $\Delta$ and $\Omega$ symbols are
available through the commands \upDelta and \upOmega; and
provides a new math alphabet \mathbold for boldface
italic letters, including Greek.
